New Technology Benefits Heart Failure Patients

Published on Friday, December 11, 2015

Technology is now available at McLaren Flint that aids in the treatment of patients diagnosed with heart failure. The CardioMEMS™ Heart Failure (HF) System from St. Jude Medical uses a miniaturized, wireless monitoring sensor that is implanted in the pulmonary artery (PA) during a minimally invasive procedure to directly measure PA pressure. Cardiologist Dr. James Chambers, and Electrophysiologist Dr. Abdul Alawwa, both inserted devices into patients on Thursday, December 3. The procedure takes place in a cath lab, where the sensor is inserted into the groin through a catheter that is guided through the body to the right side of the heart. Once in place and activated, the system allows patients to transmit information to an electronic unit. The information is stored in a secure website for clinicians to access and review. This allows for personalized and proactive management of the disease in an effort to reduce the likelihood of hospitalization.

“This technology has the potential to change the treatment of heart failure,” states Dr. Chambers, Medical Director, Cardiac Services at McLaren Flint, and one of the first specialists at McLaren to use the system. “This CardioMEMS system allows clinicians to stabilize pulmonary artery pressures by proactively managing medications and other treatment options while also providing an early indication of worsening heart failure.”

So far, studies show the sensor reduces heart failure hospital readmissions between 30 and 40 percent. Heart failure occurs when the heart is unable to pump enough blood to meet the body’s demands, and blood pressure within the heart is elevated. Significant heart failure progression over a period of days is known as acute decompensation and leads to hospitalization. Increased pulmonary artery pressures often precede indirect measures of worsening heart failure such as weight and blood pressure changes. Currently, more than five million Americans have heart failure.
